SPECIFICATION forming part of Letters Patent No. 746,025, dated December8, 1903.

Application filed December 16,1902. Serial No. 135,456. (No model.)

To all who-1n it ritrty concern.-

Be it known that i, THOMAS CHEW, a citizen of the United States,residing at Bradford, in the county of McKean and State of Pennsylvania,have invented new and useful lin provernents in Oar-Couplings, of whichthe following is a specification.

My invention relates to improvements in car-couplings, and moreparticularly pertains to that class which is automatically coupled andlocked in said position.

The object of myinvention is to provide a coupling of this character inwhich the link is more eii ectivelylocked in its operative position andthe unlocking of said means raises the link and releases it.

Another object of my invention is to provide a coupling in which theordinary link and coupling-pin can be readily and effects iveiy usedwithout injury to any of the Workparts of my invention.

A further object of myinvention is to provide a simple, cheap, and moreeffective coupling of this character than has heretofore been produced.

in the accompanying drawings, Figure l is a perspective view of mycoupling, showing the uncoupling means and the links connecting thelocking means. Fig. 2 is a vertical sectional view taken on line 2 2,Fig. 1. Fig. 3 is a transverse sectional view taken on line 3 3, Fig. 1.Fig. at is a perspective view of the coupling-links.

Referring now to the drawings, A and B represent the two members of thecoupling, which may he of any form or shape on the outside, butpreferably that shown in the drawings, and are provided with theelongated V cesses C, which have their outer ends flared at 0, like theordinary coupling, for the purpose of guiding the link to said recesses.The upper face of said recess 0 is provided with a curved recess D,whichis provided with a vertical straight wall (Z. Passing transverselythrough the said recess is a bolt or rod E, which has rigid ly connectedand carried thereby the locking member F. The said locking member hasitsupper and lower-ends beveled, and thus it will be seen that said memberis adapted to swing rearwardly within the recess, but is prevented fromswinging forward by the straight wall d. The said rod or bolt E isjournaled within the body portion of the cou pling, and one end extendsout beyond the outer surface thereof and carries a squared portion e,the purpose of which will behereinafter more fully described. The lowerportion of. the said body portion of the coupling is provided with acurved recess G, which is considerably deeper than the recess D and isprovided with a curved rear wall 9 and a forward rearwardly-extendingoblique wall 9'. Extending transverse the lower curved portion of thelower opening is a bolt or rod H, which has its ends journaled in thesides of the body portion of the coupling and has one end extending outthrough the same side as the rod E and has its extreme outer end 7tsquared, as shown. Rigidly connected to said shaft within the curvedportion of the recess G is a member I, which has a curved portion 1' tofit within the recess and astraight portion 2' to allow the hookedportion of the link to drop within the upper portion of the recess.Surrounding the outer squared ends of the rods E and H are the links Jand K, which have their outer ends and k pivoted to a vertical bar L andso arranged that when the member F, carried by the rod E, is in ahorizontal position the member I, carried by the rod H, is in a verticalposition, and vice versa. The said coupling members A and B are providedwith vertical openings M, comniunicating with the rear portion of theopenings C and adapted to receive the ordinary coupling-pin, and thus itis seen that my device can be readily used in connection with theordinary link and coupling-pin S.

The upperend of the link L carries an eye Z, and secured within said eyeis a link N, which has its upper end extending upwardly and secured to acrank-arm 0, which is carried by a rock-shaft P, which is carried by theside of thecar and adapted to oscillate. The opposite end of therock-shaft P carries an operating handle or crank Q, and upon turningsaid crank it will be readily seen that the link is readily raised andthe car uncoupled, and upon releasing said crank the weight of the linkL will throw the members F and H in the position shown on the right ofFig. 2, and thus the link is adapted to automatically couple and lockitself in said position. In order to positively lock the link in itscoupled vide a transverse opening R, which is adapted to receive a pinS, and thus it will be seen that the member F cannot possibly be swungupwardly, and thus the coupling-link T cannot be raised out of therecess G. The said link T is composed of a fiat piece of metal having atone or both ends the downwardlyextending hooked portion 25, providedwith a beveled portion 15, which is adapted to drop into the recess Gand engage the oblique forward wall g thereof. When the said linkcarries a hook at but one end, the opposite end carries a verticalopening 25 which is adapted to receive the ordinary coupling-pin whichis at all times carried by both members of the coupling.

The operation is as follows: The weight of the link L normally holds thetwo members in the position shown on the right of Fig. 2, and as thelink T enters it forces the member F rearwardly until the hook portion15 comes opposite the opening G, and then the weight of the link Lthrough the member F forces the link T into said recess G and the saidmember F looks it against any upward movement. When it is desired touncouple the cars, the link L is raised, as heretofore described, thusthrowing the member F rear wardly, so that the link T can be raised andthe member I is thrown forward and engages the beveled portion of thehook tand raises it out of the recess G, thus uncoupling the cars.

Having thus described my invention, what I claim, and desire to secureby Letters Patcut, is
